l My invention relates to shaker conveyors, and more particularly toloading devices operated by 4movement of thereciprocatory type whichcharacterizesshaker conveyors. .v

Various devices operated lby the reciprocatory movement imparted to themby a pan line have y been provided for effecting nthe delivery/ofmaterial to a pan line fi'irloading. out by the latter. Among suchdevices there are those which are adapted to be reciprocatedlongitudinally and to Q be moved bodily laterally with respect to thedirection of their pathof reciprocatory movement,

to load out material, for' example, shot coal, which has been shot downupon them or which may otherwise'be caused to rest upon them.

It is an object of my invention to provide an improved loading apparatusof the character mentioned, having a stronger'construction, a moreeffective arrangement for preventing the escape across it'of thematerial which it is intended to load out,- and improved'means forenabling it to maintain its position under, and to work its way beneath,a mass of shot coal.

More specically my invention has for one of its objects the provision ofan4 improved loading head or pan. Another object of my invention yis toAprovide an improved loading pan or head having improved meansforpreventing the 1escape of material off ofthe receding edge thereof Afurther object of. my invention is to provide an `improved loading heador pan having improved another object of my invention is to provide animproved loading pan or head having an improved construction at theforward end thereof, speaking in terms of the direction of reciprocationof such pan by a pan line. Still another object of my invention is toprovide an improved loading head or pan having an improved arrangementof reinforcing elements and elements constituting means for facilitatingmaterial penetration bythe leading edge thereof. Other objectsandadvantages 'of my inventionwill' hereina'fter more fully appear.

14 Claims. (Cl. 198-220) In the accompanying drawings there is shown forpurposesof illustration one form which the invention may assume inpractice.

In these drawings:

Fig. 1 is a plan view of an improved loading device constructed inaccordance with a preferred embodiment of my invention.

Fig. -2 is a side elevational view, from the lead, ing edge thereof, ofthe improved loading device shown in Fig. 1.

Fig. 3 is an enlarged transverse sectional View taken on the plane ofthe line 3-3 of Fig. 1.

Fig. 4 is another enlarged transverse sectional View, this on'vtaken onthe line 4-4 of Fig. 1.

Fig. 5 is a side elevational view, on an enlarged scale, of thetroughlike connecting end of the loading head or pan, showing theopposite side from that shown in Fig. 2.

Fig.V 6 is a diagrammatic plan view showing my improvedV loading devicein its illustrative embodiment in loading position in a mine room.

Referring to the drawings and first to Fig. 6, a shaker drive mechanismis shown at I. This may assume various forms, and may desirably be ofthe form which constitutes the subject matter of the application ofCharles N. Bebinger, Serial No. 595,901, led May 26, 1945, and sinceformally abandoned in view of the filing of continuationin-partapplication, Serial No. 715,526, on December '11, 1946. This shakerdrive mechanism moves a pan line 2 back and forth, outwardthat istowards the point of discharge-with a relatively slow smooth movement,so that the material on the pans will move with the latter, andinward-'towards the point from which material is to be moved-with asharply accelerated movement, so that, due to the inertia of thematerial on the pans, the pans may slide inwardly under and relative tothe material, Lwith the result that each complete reciprocation of thepan liney finds the material upon it displaced outwardly a certaindistance-normally a matter of some inches.

A swivel connection '3 is provided in the pan line at a pointsufiiciently spaced from the boob7 of material to be loaded out, topermit the requisite movement,` laterally of the face, of my improvedloading mechanism to be effected. Between this swivel connection and theface, there lie an extensible section 4 of the pan line and my improvedloading head or pan, generally designated 5. By virtue of the swivelconnection 3, the extensible section v#land Vmy improved loading` head`or .pan 5 may be swung about the aXis of the swivel to maintain asuitable relation to Vments 22 andan armed edge lsection 23,

sections may be held in their diierent positions of relative adjustment.Byv `this arrangement,

and by the addition, as needed, of further sec-Y tions to the pan line2, with relocation of the swivel 3, the loading head 5 may be relocatedas the coal face recedes, so as to be maintained in desired relation tothe face as mining out of the coal progresses. A shorter pan section 9is arranged between the pan section 1 and the loading head. or pan A5;'ia'teral feeding of the pan section 5 may be effected, by means of acable l0, an abutment jack l I, and` cable winding mechanism, hand orpower operated, diagrammatically designatedlat i2. i i l The structureof loading` head or pan 5 may be observed in Figs-..1 to 5 inclusive. Inthe preferredf embodiment therein shown, this head or pan may be notedto comprise fconnecting means Itk for effecting connection, in thearrangement 'shown to the short pan section 9, a collecting troughsection i5, and what might be called a ramp section l1, th'e latterhaving at the end v'opposite the connecting means i5 a nose portion H3,The ramp ysection l1 is made up of the top plate l'section l9,-thebottom'pl'ate section `223, a sloping rear plate section 2|, reinforcingele- Ihe Vplate section I9 is'sho'wn 'as-of a corrugated 'cross sectionon planes ltrans''verse lto the length of the ramp section. Asillustrate/d, the plate section 'l5 is provided with apluralit'y'ofrelatively plane portions separated by a plurality of convex portions-2'6 attending longitudinal-1y of the ramp section and formingas itwere, longitudinal, lro'un-ded;top ribs extending throughot `the4lengthfof the ramp section. The bottom section 2i] is, as shown,fai-least approximately plane Vto facilitate its traverse fof the minenoor, 'and vthe rear plate section 2l malg'es an obtuse angle with thebottomasection `2li. The reinforcing elements l22 areinade of platematerial having their upper edges sloping vso as to support the slopinglower side 'ofthe plate :ligand may-haveone or more rounded projections28 to fit into o'ne or more of the recesses, 42i) providedl "beneath therounded projections 26, and may also have `plane portions of the pan.The manner of bit mounting on th blocks, and of the block mounting onthe pan, may be varied, but riveting, with or without brazing or weldingmay be employed, and brazing of the bits in holes in the blocks is aneffective method of mounting the former. The reinforcing plate 34 may besecured by welding, and also by riveting common to the bit blocks, tothe plate 20.

As the pan will normally be inserted in a kerf before shooting of thecoal, so that the coal may be brought down upon it, the gauge of theplates making up the pan member will be chosen to secure adequatestrength but to avoid excessive weight. By locating the bit blocks sothat they will cumulatively maintain a level bottom thro'ghout the lfulllength of the pan as the latter is reciprocated and advanced and thenspacing the reinforcing plates 22 in correspondence with the location ofthe bit blocks, a very strongconstructionwill be provided( The nosepiece i8 tapers froinit's receding end 'to its adva'rizi'rigl end,andis'idisposed at an 'angle to the mine bottom, so that its upper'surface 36 atone side contacts the mine bottom 'and at its vother sideextends along the'varioiis piane surfaces' 25. If desired, 'abottonjpiate may be used to lend additional rigidity to themnos'e memberI8 and also a sloping 'rear platein line with the plate element '21. I-Q y The other 'ndpof Athe leading head or panV 5 inclu-des achutelil'ey :portionlwhose lbottom 38 slopes, as shown in Figs. 2 and-5, upwardly from the level 'of the bottom 'ofthe plate section 20, andthere is also av lateral ltaper lbetween the sloping sides 319 and "B0'oi the vconnecting ,pornon I6, 'so that, 'while material may be'discharged from any point within 'the `width 'of the upper corrugatedsurface of the ramp element into the wider `encl of the .ehuteuportion31, the material will be brought togetherecollected-in such a manner astopa-ss V'smocfith'ly intol'the mouth portion 42 (see Fig.- '4) 'ofthetrough section 9 4which Yis provided by the connecting 'section l5ofthe. loading head or 'pan 5..

lHerein shown asin line with each of thereinforcing plate sections `22,there are bit elements arming the pan along the Vedge thereof 'which isto be 'advancedas the paninoves laterally during loading. Herein blocks32, equipped lwith pointed bits 33, are securedt'o the forward edgeportion of the plate '20 and 'toa'thickened reinforcing bar 34 asbyrivets 35. The distance betweenV the bit carrying blocks isV desirablyso chosen that during pan reciprocation the blocks and bits will level'the bottoni Vfor the full length of the pan er 'head '5in Fig. Y1,. iAn'ear 4'6, having an'opening i "for the connection of an attachingmempe'rfas' carried at me end :or the cabi-e ,mi is arranged y"adjacent'andHjwel'djed 'to rthe saddle member `d'3; andan np'starrding 'tapering'Wall 49 is 'arranged meng the 'top for *the sidewall element 4f) andthe adjacent 'pLOlli'Oh df thjamp Se'tibh 'I1 to reduce the possibilityof "material escaping rearwardly during its shifting Yto enter theinouth portion '42, A reinforcingelementen is secured as by weldingatthe receding iside "of the head or par; s, andl this may have :eveil "towhich .a cable may ytje connecnec'i 'for puilin'gfme 'head f5 over tothe right nana "risa-fine operator doesn/t desire to bar vit 'lo'ao'l'rto that position.

According to a preferred'meth'o'd of 'use of S pld n a. vklf as 'onebackend ofthefkerf asjpossible, and the panis set in reciprocato'iyshaker motion ibe- 'tion to vroll 'down on y/to it when the `par-t which.5 smoke of shooting is 'clearing away from the working place, asubstantial mass of coal is loaded out, Vseveral cars being llable, inreasonably high coal, .before the men return to the face. If the pan hascleared itself of coal before the operator again takes over the control,he simply operates the feeding means to bring the pan under the coalagain, the bits and their mounting enabling the head or pan, whentraction is exerted on it as by the cable I0, to work its way under theshot coal. When the pan is pretty well buried, it is caused to move atsuch a rateor, better, in such steps-as will cause it to remain buriedin a position for the coal to continue to fall upon it, until it reachestheother side of the undercut and shot' coal. A.helper cleans out thefines with a shovel and throws any small amount of coal that may getacross the pan before it reaches and passes onto the trough line, backinto position to be loaded out. When the operations have been completedafter one undercutting and shooting, the mechanism may be returned tothe side at which it started, and by releasing the clamps 8 on theextension pan and/or by adding a section in the pan line section 2 andchanging the position of the swivel 3, the pan or head 5 may beplaced inposition for the next shooting. As the coal is, loaded out, say from theright rib, the undercutter may be sumped in again, and the cutter can becaused to cross the face behind the pan or head 5, though with thesetting of more jacks than Will be needed with complete separation ofthe cutting and loading operations. It will be evident that I haveprovided a simple, strong and rugged loading attachment adaptedeffectively to work its way under the coal to prevent the escape ofmaterial over its rearward edge and to resist the crushing forces towhich it will be subjected.

While there is in this application specifically described one form whichthe invention may assume in practice, it will be understood that thisform of the same is shown for purposes of illustration, and that theinvention may be modified and embodied invarious .other forms withoutdeparting from its spirit or the scope of the appended claims.
